Selecting Nouns¶

LinguaMorpha includes around 1,100 Spanish nouns. The Select Nouns screen lets you narrow these down to exactly the set you want to practise.

A segmented mode picker at the top of the screen switches between two complementary ways of selecting:

Criteria — filter by CEFR level, frequency, and topic (the standard vocabulary lens).
Noun Groups — filter by grammatical pattern: gender traps, plural class, plurale-tantum, alternate-gender pairs, false cognates, and more (the linguistic lens).

You can combine filters freely within a mode — for example A1 + A2, Very Common + Common, Food + Home gives you a focused set of everyday household and food vocabulary at beginner level.

Criteria tab¶

CEFR Level — A1 (Beginner) through C2 (Mastery). You can include one level only, or every level up to a chosen ceiling. Most learners starting out will want A1 and A2.
Frequency — Very Common, Common, or Less Common. Use this to keep your pool focused on everyday vocabulary.
Topic — limit to one or more categories: home, food, body, work, travel, technology, … The Topic list also includes any personal topics you have added yourself (see Personal topics below).

The screen always shows how many nouns match your current filters. Tap Matching nouns to browse the full list before confirming.

Noun Groups tab¶

The Noun Groups tab lets you select nouns by grammatical character instead of vocabulary scope. This is where LinguaMorpha's noun taxonomy comes into its own — a single noun can belong to several groups at once (e.g. lápiz is both z → -ces and accent-loss-in-plural), so a group filter gives you a focused drill on exactly the patterns you want to lock in.

The groups are organised into a few families:

Gender patterns — nouns whose gender disagrees with what the ending would predict (the "gender traps"), the closed Greek-origin masculine -ema/-ama/-oma set, the regular feminine-suffix and masculine-suffix patterns, and the stressed-a feminine nouns that take el in the singular (el agua, el águila).

Pair shapes — nouns that come in masculine/feminine pairs (el tío / la tía), epicene nouns with a single form for both genders (la persona), nouns whose meaning changes with the article (el capital / la capital), and heteronymous pairs (entirely different words for the masculine and feminine form: padre / madre).

Plural class — invariable nouns (the plural form equals the singular), mass nouns (typically used only in the singular), plurale-tantum nouns (only used in the plural, like los pantalones), and collective nouns whose plural references the pair (los tíos = el tío + la tía).

Plural formation — the mechanical patterns: z → -ces (lápiz → lápices), accent loss in the plural (canción → canciones), consonant + -es endings, and the small set with a stem change in the plural.

Pedagogical — false cognates (Spanish words that look like English but mean something different), and a catch-all regular group for nouns with no special pattern.

Personal topics¶

Alongside the bundled topics, you can create your own — labels like exam, tricky, or kitchen — and use them to filter nouns the same way as the standard categories.

To add a personal topic, open any noun's detail view (for example by tapping a noun in Meaning Study), tap the + at the end of the Topics row, and either type a new tag or pick from your previously-used ones. Once at least one noun carries the tag, it appears in the Topic filter on this screen, marked with a small person icon to set it apart from the bundled categories.

Personal topics are stored locally on your device and survive app updates.

Word pool vs session size¶

These are two separate things, and getting them right matters:

Your word pool is the set of nouns eligible to appear in any session — the result of your filters above. It might contain 200 nouns.
Your session size is how many of those nouns appear in a single sitting (10, 20, 30, 50, or All).

Each session, the app picks the best N nouns from your pool using your answer history. Unseen nouns appear first (ordered by significance), then weakest by correct rate. The next session picks the next best N, and so on.

If your session size is larger than your pool, all nouns in the pool are included. Setting session size to All runs through every noun in your pool in one go — useful for a thorough sweep, but demanding for large pools.

Tips¶

Start narrow. A1 + Very Common gives you about the right number of nouns to lock in core vocabulary.
Topic filters are a powerful focus tool. Going on a trip? Restrict to Travel + Food for a week.
The Select Nouns screen and the Tests share the same selection — changes here apply to every Noun drill.
